HEY GUYS & GIRLS ! I WANT TO TAP INTO A 12V HOT WIRE CLOSE TO TOP CENTER OF MY WINDSHIELD TO POWER A DASH CAM THAT WILL HANG FROM MY REAR VIEW MIRROR POST AND I SEE 2 POTENTIAL SOURCES . 1) I HAVE A WIRE ENTERING THE BACKSIDE OF MY AUTO DIMMING REAR VIEW MIRROR. 2) CLOSE TO MY MIRROR ARE THE PUSH TO ILLUMINATE CEILING READING LAMPS UNDER A PLASTIC TRIM COVER. IM NOT SURE IF THE WIRE GOING INTO THE BACKSIDE REAR VIEW MIRROR WOULD BE 12V BEING THAT THERE IS DELICATE SOLID STATE ELECTRONICS INSIDE; MIGHT BE ALREADY STEPPED DOWN VOLTAGE ;NOT SURE. I NEED 12V.. ANYONE OUT THERE INSTALLED A DASH CAM WITHOUT RUNNING A LONG POWER CORD FROM THE CIGARETTE LIGHTER. THANKYOU FOR READING MY ESSAY... STUIE

You may want to hit it with a voltmeter and see. Sorry, but that’s the best answer I have for you. And welcome. Also I’m sure someone with a lot more knowledge than I have will
Come along and answer you.
